Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an elastic insulating sheet and a switch having the same. Background Technology

[0002] A switch, as the name suggests, is a device in a communication system that performs the function of exchanging information.

[0003] In computer network systems, the concept of switching represents an improvement over the shared operating mode. A hub is a type of shared device. A hub itself cannot identify the destination address. When host A transmits data to host B within the same local area network, the data packet is transmitted via broadcast on a network based on a hub architecture. Each terminal determines whether to receive the packet by verifying the address information in the packet header. Under this operating mode, only one set of data frames can be transmitted on the network at a time. If a collision occurs, a retry is required. This method involves sharing network bandwidth, which is where switches come in.

[0004] The most common type of switch is the Ethernet switch, while other common types include telephone voice switches and fiber optic switches.

[0005] In existing switch designs, a typical power supply module 50 consists of a metal casing and a power module 50 installed at the bottom of the casing. Due to EMI / EMC safety regulations, the upper part of the power module 50 needs to be kept away from other metal components. If space is insufficient, a plastic insulating sheet needs to be attached to the bottom surface of the upper metal component to meet safety requirements. The designed switch's metal casing typically includes a base plate for securing the power module 50, a front panel 402 integrally formed with the base plate and arranged vertically, and a top cover 403 for covering the power module. The upper end of the front panel 402 is bent backward at a 90-degree angle to form a front support 4021. The front end of the top cover 403 is stacked and fixed on the upper surface of the front support 4021. For details, please refer to the appendix to this application specification. Figure 7 As shown.

[0006] The insulating sheets to be installed generally include insulating sheet A3000 and insulating sheet B4000. Insulating sheet A3000 is adhered to the bottom surface of the corresponding upper cover plate 403 in the area not covered by the corresponding front support 4021. Insulating sheet B4000 is adhered to the bottom surface of the corresponding front support 4021. In actual operation, the insulating sheet B4000 adhered to the bottom surface of the corresponding front support 4021 is adhered from bottom to top, which makes it difficult to adhere and the position is inaccurate. As a result, the bottom surface of the corresponding front support 4021 will have an exposed part facing the installed power module 50. In addition, the right edge of the bottom surface of the corresponding front support 4021, which contacts the bottom surface of the corresponding upper cover plate 403, will also have a cutout instead of being covered by an insulating sheet. This will also expose the installed power module 50, so the installed power module 50 cannot be well protected and there is a risk of safety failure.

[0007] Meanwhile, since the insulating sheets to be installed include separately installed insulating sheets A3000 and B4000, they need to be installed in a specific order, which makes the installation time-consuming and labor-intensive. Furthermore, if it is found that the installation position is inaccurate, it needs to be torn off and reinstalled, which also increases the cost of use.

[0008] In response, the inventor of this patent, drawing on work experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems.

[0017] According to one embodiment of the present invention, the upper surface of the first insulating sheet is formed as an adhesive surface A; the side of the second insulating sheet opposite to the upper surface of the first insulating sheet is formed as an adhesive surface B.

[0018] According to one embodiment of the present invention, both the first insulating sheet and the second insulating sheet are made of plastic, rubber, polyester film or vulcanized fiber.

[0019] To achieve the second objective mentioned above, the switch according to the present utility model includes a metal casing and a power module installed inside the metal casing, and also includes the elastic insulating sheet as described above.

[0023] The first insulating sheet is adhered to the bottom surface of the upper cover plate; the second insulating sheet is adhered to the bottom surface of the front support portion.

[0024] According to one embodiment of the present invention, the second insulating sheet is folded to the upper left of the first insulating sheet so that the side of it facing the upper end face of the first insulating sheet forms an acute angle with the upper end face of the first insulating sheet;

[0025] The upper end face of the first insulating sheet is adhered to the lower bottom surface of the upper cover plate; the side of the second insulating sheet facing away from the upper end face of the first insulating sheet is adhered to the lower bottom surface of the front support portion.

[0026] The beneficial effects of this utility model are:

Compared with the prior art, which requires two separate insulating sheets to be attached in two steps, the elastic insulating sheet of this application can be attached quickly in one go, which can greatly improve the attachment efficiency.

[0028] Secondly, since the first and second insulating sheets of the elastic insulating sheet described in this application are integrally formed, there are no gaps at their connection points.

This results in high safety for the switch described in this application.

[0029] Thirdly, since the first and second insulating sheets of the elastic insulating sheet described in this application are integrally formed without any gaps at their connection, there is no need to consider the accuracy of the mounting position of the elastic insulating sheet on the inner wall of the metal casing of the switch described in this application. Even if there is a slight deviation in the mounting position, it will not affect its overall use. This eliminates the trouble of having to peel off and re-mount the sheet due to inaccurate mounting position, as described in the background art, and makes the elastic insulating sheet described in this application have low usage costs.

[0030] Fourthly, the designed second insulating sheet not only separates the front support of the metal housing of the switch from the power module, but also has a sliding guide function to save time and effort in use.

[0062] The following describes in detail, with reference to the accompanying drawings, an elastic insulating sheet 1000 and a switch 2000 having therein, embodiments of the present invention. Example

[0063] Reference Figure 1 and Figure 2 As shown;

[0064] The elastic insulating sheet 1000 provided according to the embodiment of the present utility model includes a first insulating sheet 10 and a second insulating sheet 20; the first insulating sheet 10 and the second insulating sheet 20 are integrally formed, and their connection points form an included angle.

[0065] Based on the above, it is clear that this application is mainly used as an elastic insulating sheet 1000 in specific implementation.

[0066] Specifically, when applying this application, for products that require the mounting of insulating sheets, such as the corners where structural components are connected on the inner surface of the switch 2000 housing, the connection between the first insulating sheet 10 and the second insulating sheet 20 can be set at a certain angle so that the adapter can be properly attached to the desired mounting position, thereby separating the switch 2000 housing from the power module 50 installed inside, and ensuring that the installed power module 50 meets safety requirements.

[0067] Clearly, the use of this application as described above will have the following technical effects:

[0068] On the one hand, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed, this application can be applied to the corresponding application position in one go. Compared with the prior art, which requires two separate insulating sheets to be applied in two steps, this application can be applied quickly in one go, which can greatly improve the application efficiency.

[0069] On the other hand, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed, there are no gaps at their connection points, which can better separate the outer shell of the switch 2000 from the power module 50 installed inside, so that the installed power module 50 meets the safety requirements and can be well isolated and protected, making the switch 2000 using this application highly safe.

[0070] Furthermore, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed without any gaps at their connection, there is no need to consider the accuracy of the mounting position of this application. Even if there is a slight deviation in the mounting position, it will not affect the use of this application. This eliminates the trouble of having to peel off and re-mount due to inaccurate mounting position as described in the background art, resulting in low usage cost of this application.

[0071] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0072] Furthermore, in a specific implementation, according to one embodiment of the present invention, the first insulating sheet 10 has a connecting edge A, and the second insulating sheet 20 has a connecting edge B, wherein the connecting edge A and the connecting edge B are integrally formed.

[0073] In other words, in this application, the part where the first insulating sheet 10 and the second insulating sheet 20 are connected is a straight folded edge.

[0074] Furthermore, according to one embodiment of the present invention, a crease 30 is formed between the connecting edge A and the connecting edge B;

[0075] When the first insulating sheet 10 and / or the second insulating sheet 20 are bent along the crease 30, the included angle between the first insulating sheet 10 and the second insulating sheet 20 is adjustable.

[0076] Therefore, it can be clearly understood that in actual use of this application, the first insulating sheet 10 and / or the second insulating sheet 20 can be bent along the crease 30 according to actual needs, so that the included angle between the first insulating sheet 10 and the second insulating sheet 20 can be adjusted to the required size, and then the first insulating sheet 10 and the second insulating sheet 20 can be attached to the position to be attached.

[0077] Furthermore, in a specific implementation, according to one embodiment of the present invention, the periphery of the first insulating sheet 10 is chamfered to form a smooth anti-puncture portion A101; the periphery of the second insulating sheet 20 is chamfered to form a smooth anti-puncture portion B201.

[0078] This makes the edges of the first insulating sheet 10 and the second insulating sheet 20 very smooth, resulting in good anti-puncture effect and making it less likely to puncture the user during use, thus ensuring the safety of this application.

[0079] Preferably, in this technical solution, according to an embodiment of the present utility model, the crease 30 is provided along the front-back direction, the second insulating sheet 20 is provided on the left side of the first insulating sheet 10, and the second insulating sheet 20 is folded upward and to the right along the crease 30 so that the side of it facing the upper end face of the first insulating sheet 10 forms an acute angle with the upper end face of the first insulating sheet 10.

[0080] Furthermore, based on this, according to one embodiment of the present invention, the upper end face of the first insulating sheet 10 is formed as an adhesive surface A; the side of the second insulating sheet 20 facing away from the upper end face of the first insulating sheet 10 is formed as an adhesive surface B.

[0081] Therefore, the adhesive surface A formed on the upper end face of the first insulating sheet 10 and the adhesive surface B formed on the side of the second insulating sheet 20 facing away from the upper end face of the first insulating sheet 10 can be respectively attached to the required mounting position to use this application.

[0082] It should be noted that, according to one embodiment of the present invention, the first insulating sheet 10 and the second insulating sheet 20 are both made of plastic, rubber, polyester film or vulcanized fiber.

[0083] Specifically, when both the first insulating sheet 10 and the second insulating sheet 20 are made of plastic, they are preferably made of PET, PC, PVC or PI; when both the first insulating sheet 10 and the second insulating sheet 20 are made of rubber, they are preferably made of EPDM or silicone rubber; when both the first insulating sheet 10 and the second insulating sheet 20 are made of polyester film, they are preferably made of EPDM or silicone rubber. Example

[0084] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown;

[0085] The switch 2000 according to an embodiment of the present utility model includes a metal housing 40 and a power module 50 installed in the metal housing 40, and also includes an elastic insulating sheet 1000 as described in the first embodiment above.

[0086] The elastic insulating sheet 1000 is adhered to the inner wall of the metal housing 40 to separate the metal housing 40 from the power module 50.

[0087] Thus, the present application in Embodiment 2 also has a good usage effect, specifically:

[0088] On the one hand, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed, this application can be applied to the inner wall of the metal shell 40 in one go. Compared with the prior art, which requires two separate insulating sheets to be applied in two separate times, this application can complete the application in one go, which can greatly improve the application efficiency.

[0089] On the other hand, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed, there are no gaps at their connection points. This allows for better separation between the metal casing 40 of the switch 2000 and the power module 50 installed inside, ensuring that the installed power module 50 meets safety requirements. The installed power module 50 receives better isolation and protection, resulting in high safety when using the switch 2000 of this application.

[0090] Furthermore, since the first insulating sheet 10 and the second insulating sheet 20 of this application are integrally formed without any gaps at their connection, the accuracy of the mounting position of this application does not need to be considered. Even if there is a slight deviation in the mounting position, it will not affect its overall use. This eliminates the trouble of having to peel off and re-mount due to inaccurate mounting position as described in the background art, resulting in low usage cost of this application.

[0091] Furthermore, in a specific implementation, according to one embodiment of the present utility model, the metal casing 40 includes a bottom support plate 401 for fixing the power module 50, a front panel 402 connected to the bottom support plate 401 and formed integrally with it and arranged vertically, and an upper cover plate 403 for covering the power module 50.

[0092] The front panel 402 is bent backward at ninety degrees to form a front support portion 4021; the front end of the upper cover plate 403 is stacked and fixed on the upper surface of the front support portion 4021.

[0093] Based on this, in this application, the first insulating sheet 10 is adhered to the bottom surface of the upper cover plate 403; the second insulating sheet 20 is adhered to the bottom surface of the front support portion 4021.

[0094] As a preferred embodiment, in the technical solution of this application, according to an embodiment of the present utility model, the first insulating sheet 10 has a connecting edge A, and the second insulating sheet 20 has a connecting edge B, wherein the connecting edge A and the connecting edge B are integrally formed.

[0095] Specifically, a crease 30 is formed between the connecting edge A and the connecting edge B; when the first insulating sheet 10 and / or the second insulating sheet 20 are bent along the crease 30, the included angle between the first insulating sheet 10 and the second insulating sheet 20 is adjustable.

[0096] Furthermore, in specific implementation, the periphery of the first insulating sheet 10 is chamfered to form a smooth anti-puncture portion A101; the periphery of the second insulating sheet 20 is chamfered to form a smooth anti-puncture portion B201.

[0097] Furthermore, in a specific implementation, the crease 30 is set along the front-to-back direction, the second insulating sheet 20 is set on the left side of the first insulating sheet 10, and the second insulating sheet 20 is folded upward and to the right along the crease 30 so that the side facing the upper end face of the first insulating sheet 10 forms an acute angle with the upper end face of the first insulating sheet 10.

[0098] Meanwhile, based on this, the upper surface of the first insulating sheet 10 is formed as an adhesive surface A; the side of the second insulating sheet 20 facing away from the upper surface of the first insulating sheet 10 is formed as an adhesive surface B.

[0099] In other words, in the preferred embodiment of this application, the second insulating sheet 20 is folded to the upper left of the first insulating sheet 10 so that the side of it facing the upper end face of the first insulating sheet 10 forms an acute angle with the upper end face of the first insulating sheet 10.

[0100] Wherein, the adhesive surface A formed on the upper end face of the first insulating sheet 10 is adhered to the lower bottom surface of the upper cover plate 403; the adhesive surface B formed on the side of the second insulating sheet 20 facing away from the upper end face of the first insulating sheet 10 is adhered to the lower bottom surface of the front support portion 4021.

[0101] In this regard, it is clear that when using the elastic insulating sheet 1000 with the structure described in the previous paragraph, a layer of adhesive is first applied to the adhesive surface A and the adhesive surface B. Then, the elastic insulating sheet 1000 is moved from the right end of the bottom surface of the upper cover plate 403 to the left until the left end of the second insulating sheet 20 abuts against the upper part of the right end surface of the front panel 402. Then, force is applied to push the elastic insulating sheet 1000 upward. In this way, the first insulating sheet 10 of the elastic insulating sheet 1000 is quickly attached and fixed to the bottom surface of the upper cover plate 403, and the second insulating sheet 20 of the elastic insulating sheet 1000 is quickly attached and fixed to the bottom surface of the front support 4021.

[0102] Regarding the aforementioned operation process, since the second insulating sheet 20 is folded to the upper left of the first insulating sheet 10, so that the side facing the upper end of the first insulating sheet 10 forms an acute angle with the upper end of the first insulating sheet 10, the right end of the second insulating sheet 20 is tilted upward relative to the horizontal plane where the first insulating sheet 10 is located. Its upper end face is lower on the left and higher on the right, forming a slope. Under the guiding effect of its slope, it can slide well from right to left to the bottom surface of the front support 4021. In this way, it is convenient to quickly slide the elastic insulating sheet 1000 to the correct installation position for fixing.

[0103] Therefore, the structural design of the elastic insulating sheet 1000 described in this application is not simply to fold the second insulating sheet 20 to the upper left of the first insulating sheet 10 so that the side of the second insulating sheet 20 facing the upper end face of the first insulating sheet 10 forms an acute angle with the upper end face of the first insulating sheet 10. This design still has a very prominent substantial technical effect.

[0104] In simple terms, the designed second insulating sheet 20 not only separates the front support 4021 from the power module 50, but also has a sliding guide function to save time and effort in use.

[0105] It should be added that, in specific implementation, according to the switch 2000 provided in the embodiment of this utility model, the first insulating sheet 10 and the second insulating sheet 20 of the elastic insulating sheet 1000 are also made of plastic, rubber, polyester film or vulcanized fiber.

[0106] It should also be added that, in specific implementation, the elastic insulating sheet 1000 described in this application is not only used in the switch 2000, but can also be used in other places where there is a need. Specific examples will not be described here.

[0107] Other embodiments, etc., will not be described here.

[0108] In summary, the elastic insulating sheet 1000 and the switch 2000 having it provided in this application, in specific implementation, since the first insulating sheet 10 and the second insulating sheet 20 of the elastic insulating sheet 1000 are integrally formed, the elastic insulating sheet 1000 can be attached to the inner wall of the metal shell 40 of the switch 2000 in one go. Compared with the prior art, which requires two separate insulating sheets to be attached in two steps, the elastic insulating sheet 1000 of this application can be attached quickly in one go, which can greatly improve the attachment efficiency.

[0109] Furthermore, since the first insulating sheet 10 and the second insulating sheet 20 of the elastic insulating sheet 1000 described in this application are integrally formed, there are no gaps at their connection points. This allows for better separation between the metal casing 40 of the switch 2000 described in this application and the power module 50 installed inside, ensuring that the installed power module 50 meets safety requirements and receives good isolation and protection. This results in high safety for the switch 2000 described in this application.

[0110] Furthermore, since the first insulating sheet 10 and the second insulating sheet 20 of the elastic insulating sheet 1000 described in this application are integrally formed without any gaps at their connection, there is no need to consider the accuracy of the mounting position of the elastic insulating sheet 1000 on the inner wall of the metal casing of the switch 2000 described in this application. Even if there is a slight deviation in the mounting position, it will not affect its overall use. This eliminates the trouble of having to peel off and re-mount the sheet due to inaccurate mounting position, as described in the background art, and makes the use cost of the elastic insulating sheet 1000 described in this application low.

[0111] Furthermore, the elastic insulating sheet 1000 and the switch 2000 with it provided in this application are indeed highly practical and have excellent performance, which makes this application have great market promotion value and will certainly be very popular and effectively popularized.
